ADJUSTABLE STAY FOR DOORS AND GATES.

Specification of Letters Patent.

Patented Feb. 24:, 1914.

Application filed. November 13, 1913. Serial No. 800,768.

To all 'w/umi it may concern Be it known that I, MARTIN A. CHRISTEN- SON, a citizen of the United States, residing at Northfield, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in Adjustable Stays for Doors and Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a simple and efficient stay or device for taking the sag out of doors, gates, and the like, and, to this end, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The device is particularly adapted for use in connection with screen doors, which, as is well known, nearly always sag under use, so that they must, from time to time, be planed off at their lower swinging edges.

My invention provides an extremely simple device which, if applied while the door is still in form, will hold the same in form, or, if applied after the door has sagged, will draw the same back into its true form.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a view in elevation, looking at the outer face of a screen door, and showing my improved stay applied thereto; Fig. 2 is a plan view of the notched bar, removed from the door, on an enlarged scale, some parts being broken away; Fig. 3 is a side elevationof the same; Fig. 1 is a transverse section taken on the line a m of Fig. 8; and Fig. 5 is a plan view of the punched blank from which the notched bar is formed.

In the drawings, the improved device is shown applied to an ordinary screen door made up of the following parts,latch stile 1, hinge stile 2, upper, lower and intermediate rails 3 connecting said stiles, and screen panels 1.

Referring to the improved device, .the same preferably comprises a stay wire or similar brace member, a pair of anchoring plates, and a notched bar for adjustably holding the intermediate portion of the stay wire deflected out of a direct line between ner.

its anchored ends, thereby placing the same under tension. One of the anchoring plates 5 is secured. to the upper end of the hinge stile 2, and the other is secured to the lower end of the latch stile 1. The anchoring plates 5 may be secured to the door by any suitable means, such as wood screws, or they may be in the form of caps embracing the diagonal opposite corners of the door. The ends'of the stay wire 6 may be secured to the anchoring plates 5 in any suitable man- As shown in the drawings, the stay wire 6'is secured to the anchoring plates 5 by means of laterally projecting perforated studs secured thereto, through which the ends of the stay wire 6 project. The stay wire 6 is held against removal from these studs by nuts having screw-threaded engagement with the outer projecting ends of the stay wire 6.

The notched bar 7, provided for placing the stay wire 6 under tension, is formed with a longitudinally extended intermediate rib 8, having formed therein longitudinally spaced notches 9 affording hooks 10. As shown in Fig. 5, the bar 7 is preferably formed from a piece of fiat metal having cut or punched therein, at its intermediate portion, a plurality of longitudinally spaced horseshoe-like openings 11. In forming the notched bar, this plate is bent upon itself, at its intermediate portion, to afford the laterally projecting, longitudinally extended rib 8. The stock between the openings 11 form the hooks 10. In some instances, it might be desirable to form the notches on the bar 7 by providing the same with a plurality of laterally projecting, longitudinally spaced projections.

The notched bar 7 is rigidly secured, by screws or other suitable means, to the intermediate rail 8, and extends longitudinally thereof. This notched bar 7 is offset from the vertical center of the door toward the hinge stile 2, with its hooks arranged to extend toward said stile. The intermediate portion of the stay wire 6 is secured deflect-ed out of a direct line between its anchored ends by any one of the hooks 10, depending on the tension desired to be placed thereon. In case the stay wire 6 should stretch, after continued use, the slack may be taken out of the same by adjusting the stay wire on the notched bar.

The improved device is of small cost to manufacture, and is very eflioient for the purpose had in View.

What I claim is:

l. The combination with a door, of a staywire anchored at its ends to diagonal opposite corners of said door. and a notched bar applied to the intermediate portion of said door, said stay-wire having direct engagement with the notches of said bar, for deflecting the same out of a direct line between its anchored ends.

2. The combination with a door having an intermediate horizontal rail, of a staywire anchored at its ends to diagonal opposite corners of said door, and a notched bar applied to and extending longitudinally with said rail, said stay-wire having direct engagement With the notches of said bar,
